The eye exercises that have been passed down from generation to generation for more than 40 years have resulted in the second highest myopia rate in the world among Chinese students. The “uselessness” and “destruction” of eye exercises have left many parents confused as to whether eye exercises are effective or ineffective in preventing myopia. Should we do eye exercises or not? Although there is no in-depth scientific theory, multi-center clinical trials to prove that doing eye exercises can really prevent myopia, its benefits to the eyes are obvious. Eye exercises are a comprehensive measure to prevent myopia by using the principles that cause myopia, such as massage and acupressure in Chinese medicine. The meridian system is similar to the blood circulation system and is distributed throughout the body. If there is a disorder in one part of the body, it will cause disease. The acupressure of eye exercises is to remove the obstacle, so that the meridians are unblocked, which is a physical therapy. This weak acupressure stimulation, through the reflexes of nerves, to strengthen the overall tissue metabolism, improve and enhance blood circulation, eliminate and regulate eye tension, restore the body’s physiological functions, thus playing a role in the prevention of myopia. Prevent myopia 6 tricks 1, good lighting Poor lighting quality is one of the factors that cause myopia in children and adolescents. Poor lighting quality mainly has low desktop illumination, low uniformity of illumination, light strobe, glare, etc.. Too strong or too dark light will have an effect on the eyes. Too bright light will feel blinding or dazzling, ciliary muscle is tense, easily lead to eye fatigue and thus myopia. Therefore, you should choose non-stroboscopic, good light source of overhead lights, desk lamps, avoid learning in a strong or dark environment. 2, the appropriate distance between the eyes too close or too far, reading and writing posture is not correct, are important causes of myopia in children and adolescents. Desks and chairs on the high side, children and adolescents will be low and waist, deviating from the correct distance of vision; if the desks and chairs are too low, it will make the head lean forward, the spine is bent, the chest is pressed, eye regulation will be relatively tense, so that eye fatigue, over time, it is easy to myopia. Parents are best to choose for the child can be adjusted desk and chair, so that with the growth of the child’s height, adjust the height of the desk and chair at any time. 3, standardized posture Correct reading and writing posture is vital to the physical development and vision protection of children and adolescents. The most common wrong reading and writing posture is to read and write with a crooked head, or the habit of lying down and reading with a low head. Reading and writing posture should be correct, books and eyes to maintain a foot distance; book plane and the angle of vision as far as possible to maintain 90 degrees, so that the image formed on the retina is the clearest. A fist distance should be maintained between the body and the desk. Keep an inch distance between your hand and the tip of the pen when holding the pen. This process requires constant reminders and corrections from parents and teachers. 4, control of electronic products cell phones, tablets and other electronic products, their screens are made of small flash gathered, continuous use of more than half an hour on the child’s eyes is very large stimulation. Therefore, the child should be within 15 minutes of each exposure to electronic products. 5, increase outdoor sports A meta-analysis shows that the length of time spent outdoors each week is related to the prevention of myopia, with each additional hour of outdoor activity per week reducing the chances of myopia by 2%. This corresponds to a 13% reduction in myopia for each additional hour of outdoor activity per day. Studies in Sydney and Taiwan have also confirmed that outdoor activities can reduce the incidence of myopia and lower the prevalence of myopia in children. 6, medical optometry, timely prescription Due to the lack of professional knowledge of optometry, many parents are reluctant to dilate the pupils for optometry, in ordinary optical stores casually give their children a pair of glasses, not knowing that the main sense of inaccurate optometry, prescription prescription misconduct, glasses structure is not suitable, will hurt the child’s eyes, resulting in the development of myopia. Some children are found to be myopic, parents do not give their children glasses in time for treatment, but in turn promote myopia growth too fast. Therefore, the most effective way to prevent and control myopia is to assist in timely prescription of glasses based on scientific medical optometry, and to urge children to use their eyes reasonably and maintain good eye habits.
